+# By default, the library and the encoder is configured for only one output bit
+# depth. Meaning, one has to rebuild libx265 if (s)he wants to produce HEVC
+# files with a different bit depth, which is annoying. However, upstream
+# supports proper namespacing for 8bits, 10bits & 12bits HEVC and linking all
+# that together so that the resulting library can produce all three of them
+# instead of only one.
+# The API requires the bit depth parameter, so that libx265 can then chose which
+# variant of the encoder to use.
+# To achieve this, we have to build one (static) library for each non-main
+# variant, and link it into the main library.
+# Upstream documents using the 8bit variant as main library, hence we do not
+# allow disabling it: "main" *MUST* come last in the following list.
